FLOOR OR LIKE BRUSH- SPEGIFIGATION forming part of Letters Patent No.757,831, dated April 19, 1904. Application filed November 18, 1902.Serial No. 181,903. (No model.)

To all whom, it may concern.-

Be it known that I, FRANZ N EIDENBACH, a subject of the Emperor ofAustria-Hungary, residing at 1 Via del Pino, Fiume, Austria- Hungary,have invented certain new and useful Improvements in Floor or LikeBrushes, (for which I'have made application for Letters Patent inHungary, N 0. 12,148, dated September 11, 1902, and in Great Britain,No. 21,477, dated October 2, 1902,) of which the following is aspecification.

The invention relates to brushes for polishing floors.

The object of the present invention is to improve the construction ofbrushes for polishing floors, and to provide a brush adapted to beoperated by the foot, and to enable the brush to exert pressure on afloor during both the forward and returned movements, whereby both ofsuch movements of the brush will operate to polish the floor.

The brush of the present invention is so arranged that the pressureexerted on the brush does not even need to be diminished during thereturn movement. Thus a vigorous waxing results during such returnmovement and the work proceeds quicker and with less trouble thanhitherto.

The invention consists, essentially, in elastically or flexiblyconnecting a thrust-board with the back of the brush in such a mannerthat during the work or operation it receives a relative motion againstthe brush, and in consequence of the kinetic energy arising thereby themovement of the brush, as well as the waxing or polishing, isessentially facilitated.

In the accompanying drawings one form of floor-brush according to theinvention is rep resented by way of example.

Figure 1 is a side view of the brush; Fig. 2, a longitudinal section;Fig. 3, the plan of the back of the brush; Fig. 4, a bottom view of thethrust-board.

In the embodiment of the invention illustrated the thrust-board 1, whichis worked with the foot, rests on the rollers 2, which roll between themetal surfaces 4 and 5 of the back of the brush and the thrust-board.The rollers carry the disks 8, projecting into the slots 6 and 7 in theback of the brush and the thrustboard, the movement of these rollersbeing regulated by the pins 10, projecting in the slots 9. Thethrust-board is connected with the back of the brush by means of leatherstraps 11, which limit the movement of the thrust-board in an elasticmanner. It will thus be understood that the thrust-board is allowed tomove relatively to and in advance of the brush at the commencement ofeach backward or forward movement. Therefore it is not necessary todiminish the pressure on the brush at any time, because the thrustboardattains sufiicient momentum to overcome the opposingresistance of thebrush before it is retarded by its flexible connections.

The invention is applicable to all brushes required to be reciprocatedin asimilar manner to floor-polishing brushes.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a brush for polishing floors and for other like purposes,athrust-board and flexible connections between the thrust-board and theback of the brush for enabling the said board to be moved in advance ofand relatively to the brush at the commencement of each recip rocationsubstantially as and for the purposes hereinbefore set forth.

2. In a brush for polishing floors and for other like purposes, athrust-board, flexible connections for attaching the same to the back ofthe brush but for allowing relative movement, and antifriction-rollersbetween said board and brush substantially as and for the purposeshereinbefore set forth.

3. In a brush for polishing floors and for other like purposes, athrust-board, flexible connections for attaching the board to the brushbut for allowing relative movement between the two, friction-rollersbetween the board and brush, slotted disks on the ends thereof and pinson the board and brush engaging in the slots in the disks substantiallyas and for the purposes hereinbefore set forth.

4. A device forpolishing floors and for like purposes, comprising abrush, a loose thrust board on the back thereof, and means forlimitingthe relative movement between said board and brush, substantially asdescribed.

5. A device for polishing floors and for like purposes, comprising abrush, a loose thrustboard on the back thereof, antifriction devicesbetween the board and back, and means for limiting the relative movementbetween sai board and brush, substantially as described.

6. A device for polishing floors and for like purposes comprising abrush, a loose thrustboard on the back thereof and connected thereto byflexible connections, and antifriction devices between said board andback, substantiallyas described.

7. A device for polishing floors and for like purposes, comprising abrush, a loose thrustboard on the back thereof and connected thereto bystraps, antifriction-rollers between the board and back, slotted diskson the ends of the rollers, and pins on the board and brush engaging inthe slots in the disks, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
